I just bought a 30" high, 48" Long and 24"wide 150 gal tank. I plan to light it with a 270 watt Coralife 6700k fixture. Is this enough light for a high tank?
What lighting would you recommend for a 4'x2'x3'tall tank? I was thinking 2 of the 250 w halides? I'd like to Hank them 6-10" above the waters surface. Also should I go with 6700k or 8000k?

If you go 250mh I would hang them at LEAST 1 METER above the water surface.....
Depends on your growth goals of course, but 2x250w MH 6-10" over the surface will be like the surface of the sun.. I would think PAR values in excess of 1500-2k!!!!!
I have a 180 and had 3X150W mh suspended almost 40" above the surface and still got PAR of 100 at substrate....
Temp or K rating is entirely up to you and what YOU like best...IME I have found 5k-8k to be most pleasing...the 10-14K tend to be whitish/bluish and a bit colder...
The plants DO NOT CARE unless the bulbs are actinic only in which case they would care a lot more IMO...
